A-knob op- ,Fig is asimilar view` of` the same, eratedlever arm 12 extends through the 105 partly in section, and .showingi Vthe latch opening. 10 and has sleeve or hub 13 bolt in release position and locked in such Whichis mounted for tnrninr.r movement in plositionby thedetent pin3 and also showing; epenings in opposite sides of the lock case.,

Vnotches l5 in its rear side.

Said varm 'l2 has Said notches are engaged by the hooked inner ends of coiled springs 16 which are arranged above and below the latch bolt and the iront ends of which are hooked to lugs 17 which secured to the trontend of the lock case by headed shanks 18. mally cause the arm 12 to hold the Vlatch bolt in engaged or shot position, as shown in Fig. land Fig. 4t.

The usual knob shank, not here shown, extends through a square opening 19 with which the hub or sleeve 13 is provided. ln the upper side oi the latch bolt are openings as shown at lin Fig.

' 20, 21 to receive the lower en'd of a detent pinQQ. Then said pin is engaged in the opening 20 the latch bolt is secured in release position, las shown in Fig. Q', and the door can then be freely opened or closed without reference to the'lock. When the pin is engaged in the opening 21 the latch bolt isV then secured in locking position, so that the doorV is securely held locked, and the bolt cannot be operated either by means ot a key or by means of the knob.

The vsaid pin operates in an opening in the upper side of the lock caseand also extends through annular bosses 23, 24rwith which the lock case is provided. The boss 23 has a semi-circular flange Q5 and the pin has a cor.- respondingly shaped flange 2G. Said pin is rotatable, and when it is raised to entirely disengage the latch bolt, the pin is then partly turned so as to cause the flange 2G-to bear on the flange 25 and thereby hold said pin in such disengaged position. Before reengaging the pin with one ot the openings in the latch bolt, the pin must -be turned to cause its flange 2G to clear the flange 25 and the pin can thendrop into engaged position with either of the holes, according tothe po.- sition ot the latch bolt. To limit the extent ofthe upward movement ot the pin the same shown provided with a stop `flange 27 near its lower end.

To control theoperation of the latch bolt, I provideV a plurality o'lE key operated tumblers 28 which are pivotally mounted on the stud 6 as shown, and are provided in their iront sides with notches 29 to receive the rear or inner end oit the latch bolt. firms 30, 3l are thus formed above and below said notches, and are provided with beveled shoulders 32. for engagement with beveled notches 33 in the rear end of the latch'bolt. The said tumblers are provided on their lower sides with flangesBd for engagement by the wards 35 of the keyv36. These flanges are of various widths and the tumblers are detachablymounted on the stud 6 so that they can be arranged as may be desired and the wards 35 of the key are detachable from the key shank and may be arranged therein to agree with any desired arrangement ot rlhe said springs northe tumblers. The keyA shank has Aa bore 37 only in the outer side ofthe lock case, so that preferably the key canV beY operated only-'trom the outer side of the door.' The tu'mblers areY caused to engage theirY shoulders 532 linthe notches oit the latch bolt rby springs l2 which are here'shown as coiled springs the upper ends of which are attached to the arms 3l oitv the tumblers, the lower endsof said springs being engaged with notched studs 43 which project from opposite sides of astud plate del, the. said platebeinglseeured by screws 45 to the lower vside ot' thelock case,

as shown in Fig. 8. l o

In order to enable the tumblers to be turned to release position by personwithin the room, and withoutthe necessity of using a key, l providev a slide 4.6 whichismounted torsliding movement in the lower side of the case and which bearsagainst the underside oil the substantially semi-circular rear' portion oit'the tumblers. Y Thersaid'slide has a stem 4f? which operates in a slot 48 in the 'lower side oi? the lockncase andV alsohas a thumb piecejor nut 49 which is screwed on said stem` and isV preterablyf'also secured thereto by a pin 50. .lWhen'the slide is in the position shown inFig. l, it is entirely disen gaged from the vtumblers and the latter can only beoperated and raised to vrelease posiL tion by meansv of a key. 'li/Y hen the slide in moved to the position shown in Fig. it engages under the lower sides Vojtlthe tumblers and serves to hold them in releasedposition with respect to the Ylatch bolt, as ishownin Fig. Q. i

l'Vhile I have herein sho'wnand describedV a pr'el. .rred embodiment of my inventiorndV would-have it understood that changes may be made in the torni, proportions and construction o'li the several parts, without departing from the spirit otmy invention, and within the scope oli' the appended claims.

llThat-I claim is y l. .ln a lock.v the combination oit acase, a bolt mounted ttor sliding movement in .the

case, a -knob operated arm pivo'tally mounted in the case andengaged with the bolt, and a i springvcoact-ing withy said arm to normally hold'the bolt in shot position. K

In a lock, the combination of a case, a bolt mounted vfor movement in theY case, a knob operated arm pivotally mounted inthe case and Vengaged withthe bolt, a spring coacting'with said varmto normally'hold the bolt in shot position, and a detent element movable into and out ofengagement withV 1,465,290 f Y g said bolt and arranged to hold the same and also mounted for turning movement, either in shot or in release position.` said pin and oase having coacting means to 3. ln a lock, the combination of a case, a hold the pin in disengaged position when l0 bolt mounted for movement in the case and Said pin is turned in one position. having a plurality of openings in one side, In testimony whereof I afix my signature. and a detent pin mounted for movement in the case to engage in either of said openings, LOUIS VERDY.
